Sparrow 1.2 for iPhone allows you to compose emails in landscape mode and swipe between email threads. The app is now also available in nine total languages: English, French, German, Spanish, Italian, Japanese, Dutch, Russian, and Chinese. Great! The downside is that the developer says it's been unsuccessful in petitioning Apple to get the VoIP privilege necessary to integrate push notifications into the app the way it wanted to. Instead, push will be available as a yearly subscription in an upcoming version of the app. [iTunes and Sparrow via Ubergizmo]
